SELF-LUBRICATING BEARING FOR TROLLEY-WHEELS.

SPECIFICATION forming part of Letters Patent No. 727,015, dated May 5, 1903. ame filed December 16,1901. serial No. 86,114. on, model.)

To all whom it may concern.-

Be it known that I, CHARLES E. STANLEY, a citizen of the United States, residing at 0amton, in the county of Stark and State of Ohio, have invented new and useful Improvements in Self Lubricating Bearings for Trolley- Wheels, of which the following is a specifical.ion.

This invention relates to a self-lubricating bearing for trolley-wheels.

The object of the invention is to provide simple and effective means for automatically lubricating the shaft or spindle of a trolleywheel; and to this end the invention consists in certain novel details of construction and combination and arrangement of parts which will be hereinafter fully described, defined in the appended claims, and illustrated in the accompanying drawings, in Which- Figure 1 is a front elevation of a trolley wheel and fork embodying my invention. Fig. 2 is a side elevation of the same. Fig. 3 is a vertical transverse section through one of the arms of the fork. Fig. at is a section on the line 4 4 of Fig. 3. Fig. 5 is a detail View of the sections of one of the bearing-boxes.

Referring now more particularly to the drawings, the numeral 1 represents the trol-' ley fork or support, 2 the trolley-wheel, and 3 the shaft or spindle to which the wheel is arms of the fork into bearing-chambers 4, formed integrally upon said arms, and are journaled in bearing-boxes 5, seated in said chambers, each of which boxes is formed in two semicircular parts 6 and 7, the part 6 being preferably made of brass and the part 7' of glass. The boxes are removable through the outer open ends of the chambers 4, which are closed by suitable screw-caps 8.1 On each fork-arm below each bearing-chamber is. formed an oil-chamber 9, which is open on its outer side and is in communication with the bearing-chamber through a passage 10. The oil is conveyed'from the oil-chamber to the journal-bearing through the medium of a wick 11, which extends through said passage 10 and enters a feed opening formed by notches 12 in' the meeting faces of the journalbox sections 6 and 7, whereby the oil is supplied by capillary attraction to the shaft and The ends lubricates the parts in an obvious manner. The wick is inserted into the oil-chamber through theexterior opening in said chamber, which is-closed by'a capor cover 13, which seats against a suitable shoulder 14. This cap or cover is fastened in place by'a screw 15, passing through an opening in the cap and entering a screw-threaded socket formed in a post 16, formed upon the fork-arm. The removal of this cap or cover permits also of the cleansing of said chamber whenever required. The oil is supplied to each oil-chamher through a feed-opening 17, closed by a screw-closure 18.

From the foregoing description, taken in connection with the accompanying drawings, it is thought that the construction, operation, and advantages of my improved self-lubricating bearing will be readily apparent without requiring an extended explanation.

Various changes in the form, proportion, and the minor details of construction maybe resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described the invention, what is claimed, and desired to be secured by Letters' Patent, is i 1. In a self-lubricating bearing forltrolleywheels, the combination of a trolley-fork having each of its arms provided with an oilchamber, a bearing-chamber above the oilchamber, a passage connecting said chambers, and 'a' stud or post extending into the first-named chamber and provided with a threaded aperture, said chambers having side openings, the wall of the i first'bei'ng screwthreaded and the wall of the latter recessed, a screw-plug engaging the threaded wall of the bearing-chamber and closing said chamber, a cover-plate seated in the recess of the .oil-chamber and closing said chamber, a fastening-screw passed through the cover-plate and entering the threaded'aperture of the stud, thereby securing said plate in position, journal-boxes in the bearing-chambers, a shaft or spindle carrying a trolley-wheel and journaled in said boxes, and means for conveying oil through each connecting-passage from each oil-chamber'to the journal-boxes in the adjoining bearing-chamber, substantially as described.

2. In aself-lubricating bearing for trolleywheels, the combination with a trolley-fork having its arms provided with bearing-chambers; of journal-boxes removably seated in said chambers, each of said boxes being formed in sections having a feed-aperture, a shaft or spindle carrying a trolley-wheel and journaled in said boxes, an oil-chamber, and means for feeding oil from the oil-chamber through said aperture to the shaft and boxes, substantially as specified.

3. In a self-1ubricating bearing for trolleywheels, the combination of a trolley-fork having its arms provided with bearing-chambers and oil-chambers in communication through suitable passages, said chambers being open on their outer sides, removablejournal-boxes CHARLES E. STANLEY.
